TILTING SIDE-DUMP CAR.

Specification of `Letters Patent.

Application led October 11, 1916. Serialv No. 124,986.

To all whom t may concern: Y

Be it known that we, CHARLES H. CLARK, a citizen of the United States, and resident of Dormont, in the county of Allegheny and State of Pennsylvania, and HOWARD L. BEACH, a citizen of the United States, and resident of Edgewood, in the county of Allegheny and State of Pennsylvania, have inin Tilting Side-Dump Cars, of which the following is a specification.

This invention relates to dump cars of the general type disclosed in patents to Charles H. Clark, No. 1,007,533, October 31,1911, and Nos. 1,182,643 and 1,182,644, May 9,

. 1916, and the primary object is to improve and simplify the'mechan-ism forv transmitl ting opening and closing movements tothe doors. This feature of the invention is embodied .in means mounted on the tilting car bodycand so connected to the door and to the under frame that movement of the body' relative to the under frame will impart positive movement to the `door so that as the body begins to tilt the door on the dumping side begins to open. When body has reached its extreme tilt the door has reached its extreme opening and as the body is trac moved back toward its horizontal positionthe door is proportionally moved toward its closed position. l

The doorsextend from end to end of the bodyl and constitute the side walls thereofwhen the body is upright, the door at the lowering lside being adapted to turn outwardlyand downwardly When the car is dumped and form a chute-like extension for dire ing the discharging load clear of the k. ,As each door extends from end to end of the bodythe mechanism for` transmitting motion thereto is repeated or duplicated at such intervals asis necessary to positively control the movement Vof the door, l

thereby f0restalling\ the effect of unequal strains on'difl'erent portions of the 'door and suiiiciently-reinforcing all portions thereof to withstand the ,stress lplaced thereon whether 'the same be' equally-orpunequally distributed. *In-iconstructions-of prior design the several devices for transmitting motion to the door vhavebeen so connected thereto that sluggish or irregular movement of one mechanism would affect all the other mechanisms. In the present invention this difficulty has been overcome by so arranging the several mechanisms that each operates independently of the rest eXce ting in so far as all are mounted on the car ody and positively actuated by the movement of the latter relative to the under frame.

While the invention has particular reference to a car that is adapted to dump at either side of the track, the operating' mechanisms for each door'are quite distinct from the mechanisms for operating the other door, said mechanisms being of such design that they operate to open and close CHARLES H. CLARK, OF DORMONT, AND HOWARD L.' BEACH, OF' EDGAEWOOD, PENNSYIr Patented Mar. 9, 1920.

the door at the dumping side only, the

mechanisms at the opposite side retaining their normal door-locking position 4during the .dumping operation. While such mechanisms are ordinarily suiiicient to retain the door at the rising side in closed position, a further feature is the provision of a lock which is separate and distinct from the door actuating mechanisms, and which is so arranged that when one door is unlocked for dumping the opposite door is necessarily locked. The arrangement is such that the door actuating mechanisms at the rising side of the body are adapted to be released from the under frame and permit saidv mechanisms to rise with the body without being moved from door-locking position, such releasing mechanism also constituting the primary means for so releasing the body from the under frame as to enable it to rock in the desired direction. The releasing devices are-mounted on shafts which extend longitudinally of the car in order that the several actuating'mechanisms for the same door may be eithersecured or released simultaneously. Heretofore, these shafts have been extended through the `,under frame holsters and to the ends of the-car for 'conlneetion with levers or other operating devices. When a car 1s 1n service there 1s unavoidable slight relative movement on the shafts and holsters which is sufficient to cause the shafts to bind or to otherwise impair their operation. In the present inventionthis diliculty has beenovercome by lo l eating the latch-carrying shafts wholly between the under-frame bolsters, and providing relatively short shafts which are loosely connected to the latch-carrying shafts and which extend through the holsters to the car end for receiving the operating levers, whereby the latch-carryingy shafts are permanently retained in operative position.

In the accompanying drawings, Figure 1 is a side elevation of a portion of a side dump car constructed in accordance with the invention. Fig. 2 is a view of the car partly in end'elevation land partly in cross-section, the plane of the portion in section being indicated by line 2-2 of Fig. 1. Fig. 3 is a cross-section on line 3-3 of Fig. 1. In Fi s. y, 2 and 3 thedumping position of the car bo y Referring to the drawings, the under' frame which may be of any preferred construction is here shown as consisting of a central box girder which vextends from end to end ofthe car, the separated channel beams 2 comprising the side of the girder and plate 3 the top thereof. At each end of the car the under frame includes a bolster 4 preferably arranged centrally of the truck,

land the top of the bolster is constructed with the toothed or cogged rocker-receiving surface 5. At each end of the under frame is the upstanding Xed end frame 6 and at the outer side of the latter a platform 7.

i f The car body consists of a frame which carries Hoor 8, end walls 9 and the doorforming side walls 10, the latter hinged at 11 to the frame to turn outwardly and downwardly in continuation of floor 8 for dis charging the load clear of thetrack, as shown in dotted lines in Figs. 2 and 3. A desirable construction of the body frame consists of a centrally located beam' 12 and l the opposite side beams 13. At suitable intervals are the vertical transversely disposed diaphragms 14. At each end of the body frame is a rocker 15 which is adapted to fit and coperate with the rocker supporting face 5 of bolster 4, in the preferred adaptation the arrangement being such that the body is adapted to rock toward either side for dumping. The under frame being without side sills the body is carried quite low,

with a resulting low center of gravityfor the car, without interfering with freely 1nclining the body toward. either side when dumping.

The motion transmitting mechanismsfor the doors are located wholly beneath the body, the absence of side fsills affording ample room therefor at. each side of the central girder to which said mechanisms are i.

4operatively lconnected at such intervals throughout the length of the door as may be necessary. Each of said mechanisms consists primarily of a bell-crank lever 16 fulcrumed at 17 to the under portion. of the body frame between two separated dialphragms 14, Fig. 1. In normal position, e., with the body upright', the shorter arm of the lever is disposed downwardly while the longer arm extends outwardly toward the door to which it is connected by link 18. Link 18 is pivoted at 19 to lever 16 and at 19 to arm 2O depending from the door. When the body is upright pivot connection 19 is slightly beneath a line extending between points 17 and 19', forming a toggle construction with link 18 and lever 16 provided with the upwardlyA abutting stops 21,

' lever 16 and link 18 securely hold the door in closed position as in Fig. 2.

Pivotally connected at 17 to the depending -arm of the bell-crank 16 are links 22 which are connected by pin 23 tol a link 24,

lpivoted at 24 to the upper portionof the bifurcated upstanding bracket 25 secured to channel beam 2 of the under frame. At the lower outer side'of the bracket is the pad or bearing surface 26 against which the lower extremity of link 24 is adapted to bear and against which it is held by the engagement of pins 23 by latch hooks 27. These hooks are ixedly mounted on shaft 28 which extends from bolster to bolster and is journaled in bearings 25 in brackets 25. It is apparent that when the car body is rocked to the lhorizontal position the side door and l link mechanism on the high, non-dumping side will thrust pins 23 downwardly and links 24 will guide them into position where' they may be engaged by latch hooks 27 As best shown in. Figs. 3 and 7, secured to each end of shaft 28 is a crank 28 connected by a link 29 to a crank 30 on the inner end of an operating shaft 30. Shaft 30 extends from the end frame of the car through the bolster and is operated by an actuating lever 31 accessible at the end of the car. -With the parts thus arranged, shafts 28 terminate at the inner sides of bolster 4 and are in no way affected by relative movementof the bolster and 'shaft as might result if said shafts were continued lthrough the bolster. Link 29 is slotted at 29 where it connects with crankA 28', lso that shaft 2`8 maybe operated by shaft 30y at either `end ofthe car without moving the corresponding shaft 30 at the" opposite end. Shaftsl 28 are cross connected by the tension device 32 secured to arms 32',v y i whereby the oppositeflatches are normally "held under tension in positive engagement with pins 23, thereby locking the body se- Operation: The first step is, to release latches 27 from pins 23 on the non-dumping- Vcurely in upright position while in transit.

side of the car \as shown on the left hand side of Fig. 2, so that when the body is tilted to the position shown by dotted lines in Figs. 2 and 3 the linkmechanism attached tothe non-dumping side will rise with the dbody and maintain its door locking position. l

On the dumping side the downward movenient of the bodybreaks the toggle 17, 19, 19 and at the eXtreme tilt the link lmechanismI assumes the position shown in Fig. 6. The'fraising of toggle pin 19 to this position causes the door to open on hinge pin 11 to the position shown. When the body is returned to normal position the reversed movement of the link mechanism closes the door.

. As heretofore noted, the motion transmittingniechanisms are arranged at such intervals throughout the length of the door as maybe necessary, and it is further charac-A teristic of the construction that each ofsaid mechanisms operates independently of the other mechanisms excepting as all are affected and -controlled by the movement of the body, with the result that any undue defiection or other disturbing. influence." that may even slightly affect one of said mechanisms will have no effect on the others.

` While the motion transmitting mechanism will be ordinarily sufficient to hold the door at the rising side securely locked as in Vdotted lines in Fig. 2, to guard against any possibility of the joint being sprung between levers 16 and link 18, a lock is provided at the end of the car for positively securing the door at the rising side. As here embodied the lock consists of a hook-,like pivoted latch 40 for each door adapted to engage pin 4:1 thereon. The opposite latches are connected by rod 42 with theJ result that when the latch is in position to release'the door at the dumpingside the other latch is necessarily in door locking position, as shown in Fig. 2.

Mechanism for rocking the body during the dumping operation comprises no portion of the present invention. The same may be variously embodied, for instance as disclosedI in any `of the above mentioned patents to Charles H. Clark.
